1 – Muhammad b. al-Hasan by his isnad from al-Husayn b. Sa`id from Safwan from Ibn Sinan – meaning `Abdullah. He said: I asked Abu `Abdillah عليه السلام about the condition regarding the slave woman that she not be sold or donated. He said: That is permissible in other than inheritance, so she is inherited, for every condition that opposes the Book is void.

2 – And from him from an-Nadr b. Suwayd from `Abdullah b. Sinan from Abu `Abdillah عليه السلام. He said: The Muslims are with their conditions (i.e. they abide by them), save every condition that opposes the Book of Allah, then it is not permissible.

3 – And by his isnad from as-Saffar from al-Hasan b. Musa the wood merchant from Ghiyath b. Kallub from Ishaq b. `Ammar from Ja`far from his father عليه السلام that `Ali b. Abi Talib عليه السلام used to say: Whoever conditions a condition for his wife then he is to fulfill it for her, for the Muslims are with their conditions, except for a condition that makes haram a halal or makes halal a haram.
